무연 압전에너지 하베스팅 기술을 활용한 자가발전형 무선 온도센서네트워크의 시험개발에 관한 연구

Abstract

Recently, a self-powered real-time monitoring system suitable for domestic situations where explosion incidents in domestic power plants is attracting much attention. By using mechanical vibration energy which is constantly generated in motors and transformers of power plants, can be converted into electricity using lead-free piezoelectric harvesting technology. The output power can be supplied to monitor real-time wireless temperature sensors that do not require a battery. In order to fabricate the high efficiency piezoelectric material, a composition with a high piezoelectric constant was designed, and the vibration in the power plant was measured to fabricate the harvesting module. In order to measure the temperature of the hazardous area in the power plant for fire protection monitoring, we successfully supplied the necessary power for the wireless network system that can receive the temperature data to the computer wirelessly with the temperature sensor and receive the data in real time to the safety manager's computer once every 1.2 seconds.
